Tesla Model X uses a fully electric high-voltage A/C compressor to provide cabin cooling and dehumidification. Instead of a belt-driven unit, this sealed compressor is powered directly from the traction pack and controlled by the thermal management ECU for variable-speed operation and high efficiency.
The unit offered here is the correct OEM-style A/C compressor for Tesla Model X, Tesla P/N 1042442-00-M (and compatible revisions in the 1042442-00-x family). It fits all Model X vehicles built roughly Sept 2015 – Feb 2021 that use the original R134a-based thermal system.
